  • RE: TPS55288: 11 kHz Ringing from Vout During Low Output Current

    Resolved
    Hi Bruce, I got around to testing this, and it's much better in FPWM mode. The audible tone goes away and the ripple decreased significantly. Thank you for this recommendation and for the resistor swap recommendations as well. Best regards, Cory
